A new multiple faces detection method based on facial features is proposed, which gets the face candidates with the help of skin color and makes use of wavelet express of images and the principal component analysis (PCA) to obtain the eigenvectors distinguishing faces and non-faces, and modifies Bayesian classifier to detect multiple faces of input images. ??, the parameter of the modified rules,...
Interferogram estimate method based on the weight subspace fitting is presented through the subspace fitting of measured signal subspace and the subspace spanned by compound steering vectors. The proposed method can improve the performance of interferogram estimate, using the forward-backward average processing method to decorrelate the signals. The processing results from real data of InSAS show...
In this paper, a new algorithm of face detection based on differential images and PCA in color image is proposed which modified the eigenface technique. First, skin picking-up is carried out by color analysis of an image. Then, for finding the exact positions of faces, a finer matching is performed by eigenface in these detected fields and a mosaic template is used to suppress the false face. Considering...
In this paper, we propose a wavelet lossy image coding algorithm with edge detection and tracking using wavelet difference reduction. Firstly, we obtain the edge map of an obstacle image by SUSAN edge detector. And an edge tracking filtering method is applied to the edge information image and Region of Interest (ROI) is extracted from the original image. Then the coordinates of ROI are mapped to the...
